Material analysis shows that high density nanoparticles that are well dispersed on the nanotube surface are deposited. The average catalyst particle size is between 3 and 4.5 nm depending on the sputtering conditions. The methanol oxidation current of the ternary PtRuNi catalysts increases up to a factor of 2.6 as compared to the binary PtRu catalyst. Our studies shed light on the advanced control of nanotube-supported electrocatalysts under a low loading via the vacuum deposition techniques and can contribute to the controlled synthesis and understanding of fuel-cell catalysts.

One-dimensional nitrogen-containing carbon nanostructures

“…particle size 3-4.5 nm, 2.6 higher MOR current compared to PtRu [487] Pt-SnO2 NCNTs ALD of SnO2 on NCNTs grown directly on carbon paper SnO2 around 1.5 nm, Pt NPs 1.5-4 nm. 125 times improved ORR and MOR activities [493] …”

“…[694], PtRu deposited on carbonized ionic polymer-modified CNTs [482] and Rudecorated Pt/MWNCNTs prepared by atomic layer deposition [483]. Ternary PtRuNi catalyst deposited over NCNTs provided further improvement of MOR activity by a factor of 2.6, compared to binary PtRu catalyst [487].…”

Low-energy electron elastic scattering from Mn, Cu, Zn, Ni, Ag, and Cd atoms

“…The experiment [31] found that the methanol oxidation current of the ternary Pt-Ru-Ni catalyst increased by as much as a factor of 2.6 in comparison with that of the binary PtRu catalyst. This can contribute to the controlled synthesis and understanding of fuel-cell catalysts [31]. Furthermore, the high efficiency of Ag nanoparticles deposited over activated carbon has been demonstrated in controlling microorganisms in water [32].…”

“…For example, the catalytic activity of the Au-Ag-Pd trimetallic nanoparticles was investigated and found to be efficient in catalyzing the Heck reaction [30]. The experiment [31] found that the methanol oxidation current of the ternary Pt-Ru-Ni catalyst increased by as much as a factor of 2.6 in comparison with that of the binary PtRu catalyst. This can contribute to the controlled synthesis and understanding of fuel-cell catalysts [31].…”

Spontaneous Synthesis and Electrochemical Characterization of NanostructuredMnO2on Nitrogen-Incorporated Carbon Nanotubes

“…Therefore, in the design of a composite electrode, it is ideal to fabricate an extremely thin layer (∼nm) of nanostructured MnO 2 onto the current collector, controlling the coating layer thickness and uniform surface coverage to reach the high theoretical specific capacitance. To achieve this goal, the direct-growing nitrogen-incorporated carbon nanotubes (CNxNTs) on the carbon cloth (CC) function as a hierarchical current collector, which is used to improve electronic conductivity and increase specific surface area [21,22]. Due to the incorporation of nitrogen, CNxNTs also inherently possess surface defects, creating a further increase of anchoring sites for uniform deposition of MnO 2 nanostructure, and facilitating the charge-transfer between active materials and CNxNTs.…”
